New measurement of excitation functions for (p,x) reactions on natMo with special regard to the formation of 95mTc, 96m+gTc, 99mTc and 99Mo

Cross-sections for the proton induced reactions on natural molybdenum leading to 93mTc, 93m+gTc, 94Tc, 94mTc, 95Tc, 95mTc, 96m+gTc, 99mTc, 90Mo, 93mMo, 99Mo, 90m+gNb, 92mNb, 95Nb and 89m+gZr were measured in the proton energy range 8.4–37.1 MeV on the cyclotron U-120M at the Institute of Nuclear Physics AS CR. Special attention was paid to excitation functions and thick target yields for the formation of 95mTc, a suitable tracer for 99Tc, of 96m+gTc, which was proposed as a proton beam monitor, and of 99mTc and 99Mo, the most widespread radionuclide generator pair in nuclear medicine. If appropriate, obtained data are compared with the heretofore published cross-sections.
